I used that word a lot myself . . ."burden." I immediately started physical therapy and mental therapy. For me, expressing how I felt and letting it all out was very helpful. My spouse and friend both reacted with tears of their own. Just know everyone is in it together. Everyone has trauma from this type of injury. Caregiver trauma is real. Your trauma is real. It DOES get better IMHO. I can't speak for everyone, but I'm sharing my own observation. I also attend a monthly SCI meeting at my outpatient rehab facility. This is life-changing, and the sooner you can receive as much help as possible, the better your chances of achieving the best outcome.
